"Yeah! What's your favorite thing Peter Tosh has ever done?" I asked, genuinely thrilled that I had found a music pal so early into the semester. But the kid didn't say "Get Up, Stand Up" or even "Legalize It." He gave me a blank stare and a dumb gaze that admitted he had no idea who this Tosh character was. He didn't seem to care--Bob was the man! I, on the other hand, ended the conversation and found another seat. Peter Tosh, thank you Jah, is no Bob Marley. In the 40 years preceding his 1987 murder, Tosh--an original Wailer, a masterful songwriter and a Jamaican advocate--managed to help define popular reggae, tour and record with both The Rolling Stones and Eric Clapton, and draw attention to the Jamaican gang crisis that warranted the legendary One Love Peace Concert. Tosh's music gets a second wind Friday with the help of former bass player Fully Fullwood and an all-star cast of friends. This is the first tour of its kind. It's long overdue. 10 p.m. $12; $10 with student I.D.
